Specification of Letters Patent.

Patented Nov. 2d, 191W.

Application inea March 17, 1915. serial Nol 14,922.

tically all of the advantages attendant upon the use of the ordinary wood shuttle, shall he proof against the development 'nr forming therein of splits, dents or the like and which shall at the same time be capable of' being produced at the least possible increased cost of manufacture.

In the accompanying drawings, in which the invention is fully illustrated in its preferred form,

Figure l is a plan Viewv of the improved shuttle;

Fig. 2 is a side elevation thereof;

Fig. o is a cross-section on the line in Fig. 2;

Figs. 4 and 5 are perspective views of the jacket and core in their original forms; and,

Fig. 6 is a perspective, view of the jacket, core and tip elements, assembled and before the exterior of the shuttle has been trimmed to its ultimate form.

The core a shown in Fig. 5 is a suitable length of wood preferably having its top and bottom surfaces on the one hand, and its two side surfaces on the other, parallel with each other, excepting that as to one or more of said surf es, preferably the two side surfaces., bevels are formed, as shown, to give the core a certain amount of taper at the ends thereof.

The jacket or shell which in its ultimate condition as a part of the shuttle is a tough, rainless and light material, is preferably ormed by softening a sheet, say of liber, and then pressing the saine in a'suitable mold in the shape shown in Fig. 5, which shape `intcriorly of the jacket con forms to the shape of the core a. The length of the j aeket in the preferred form is cot tensive with that of the core, which has its ends cut oft' square.

The jacket tha-ving been thus vformedV and pref AVably allowed to set until it resumes its original state of hardness, and glue or other cernes:v having been applied to all of the inside surface of the jacket, or all ol' the corresponding surface ol the core, or to both, the core is placed in the jacket and then the parts subjected to pressure so that their opposed surfaces at all points are held in intimate Contact with each other throughout;

' in thisnonditifm, the parts are left until the cement has set. The shell being open from end to end thereof (in the adaptation shown, from one side clear to the other side thereof), the assembling operation is one which is at once of the simplest character and may be made to result in the shell being shaped, even at the tapered ends of the shuttle, exactly to the form of the core.

Thereupon, the core is chambered, as at c, for the filling package and the tension means Z and the holes c` are driven through the jacket and core for the reception of the pins f which support the spindle g and its spring h. In the preferred construction, the pins j' are made a trille longer than the core is thick, so that their ends rest in the side walls of the jacket, as shown in Fig. 3. 'lhen the tip elements are attached to the end of the core, each such tip clement includin a tapered metallic tip proper il and a was ier or disk j (preferably of fiber) through which the tang of the tip proper il is driven.

Finally, the outer surface of the body thus formed is trimmed to the ultimate shape of the shuttle and polished, the sides and bottom of the jacket and the top surface of the core being made flush with the tip elements.

Since the two side and bottom walls of the jacket of the improved shuttle are integral with each other, there is no possibility for open seams to form lengthwise of the shuttle `and along its edges, and particularly the bottom edges, due to the cement being ineffective to keep the jacket walls bound to the core under the stress of violent shocks and friction to which the shuttle is constantly subjected. The jacket, by having its two side andbottom walls integral in the vicinity of the pins f, and especially where the ends of the pins rest in the side walls of thejacket, further reinforces the core of the shuttle against splitting on account of shocks or strains incident to moving the spindle on its pivoting pin; shuttles of ordinary construction often split lengthwise at one or other of these pins, and such splittingF lOO is Wholly avoided in the improved shuttle. Finally, the 'core `approximating inv length the length of the shuttle7 the structure is in effect a jacketed shuttle7 as such havingthe obvious advantage over the heretofore-proposed' shuttle-shapedshell Carrying in its ends separated core pieces for the support of the spindle and other parts that the ends of the core are solidly connected and the Whole structure is therefore perfectly adapted to withstand lthe yshocks attending its baclrand forth movements in the loom.

It is preferable, as herein described and shown, to taper the ends of the core,"sinee thereby, when the trimming of the ends of the shuttle is eii'eeted, there will be suiiicient thickness vof material in thejaeket so that upon the trimming being accomplished there.

will be no exposing as the result thereof of the core. I 4 A y Having thus-fullydescri'bed my invention, what I claim as new and desire to secure by Letters Patent is :f-y t l. A loom shuttle yincluding an elongated ehambered core extending approximately from end Ato end of the shuttle and an elongated one-piece shell of hard stilf sheet material jacketing and secured to said core and.including'a bottom and tivo side lWalls covering said core at the bottom and both sides from approximately end to end thereof, said shell being' open from endto end thereof at the vupper side. l

2. A loom shuttle including an elongated chambered core extending approximately from end to end of the shuttle and an elon gated one-piece shell of hard, stiff, sheet material jacketing and secured to said core and including tvvo or rmore adjoining Walls covering said core at tWo or more adjoining surfaces thereof from approximately end to end of said core, said shell being` open from end to end thereof.

In testimon whereof l alix my signature in presence o two Witnesses.'y y
